Sound is a vibration that travels through a medium as a wave. Freddy did an experiment to

prove this theory as illustrated below. He spread 1 tablespoon of salt on top of the bowl

which is covered with plastic wrap. He held the metal tray in the air but next to the bowl.

Then, by using a metal spoon, he hit the metal tray like a drum while observing the salt.

What is the result of this experiment?

• The salt is not moving because sound vibration cannot be transferred through

  different media.

• The salt is moving because sound vibration is transferred through air and reach the

  plastic wrap.

• The salt is not moving because sound vibration has not enough power to move thing.

• The salt is moving because sound vibration is transferred to the bowl first and then

  reach the plastic wrap.

Gravity is a force that pulls objects toward the Earth. When objects are dropped, they will

fall to the ground. However, the air has a resistance that defies gravity and creates an

upward force. This resistance causes objects to fall at different speeds. Five children did an

experiment by dropping 5 cups of the same size from the second floor onto the ground. Each of them turned the cup upside down and dropped it at the same time. Which of the

following options shows all the cups falling more slowly?

• 1-3-5

• 2-3-4

• 3-4-5

• 1-3-4

There are several characteristics that categorize plants as living things. One of the examples

is the behavior of Mimosa pudica. It is well known as ‘sensitive plant’ because its leaves will

curl when we touch them. What is the characteristic of living thing that explains the

behavior of this plant?

• Living things can move on their own

• Living things will die without oxygen

• Living things adapt to their environment

• Living things respond to stimuli

One late afternoon, Kaito did an experiment by sticking a bar magnet with a tape to a

styrofoam plate to observe whether magnet can be used as a compass. When he put the

styrofoam plate on the water and turned it a few times, it finally stopped. In which direction

would the South pole of the magnet be pointing?

• A

• B

• C

• D

Jib and Sua did an experiment by blowing out a candle as illustrated below. Each of them

blew a candle which was placed behind an object. Jib used a round-shaped object while

Sua used a square-shaped one. The shape of objects will give a different impact to the air

movement. When they blew out the candles at the same time, whose candle would put

out easier and why?

• Jib’s candle; it is because the air spreads in all direction.

• Sua’s candle; it is because the air goes around the object.

• Jib’s candle: it is because the air movement follows the shape of the object.

• Sua’s candle; it is because the shape of the object makes the air move easier.

Puffer fish is mostly found in tropical and subtropical ocean. This fish has elastic stomach

that allows it to quickly take large amount of water to transform into a bigger size. What is

the purpose of that behavior?

• To draw attention of their preys.

• To get more oxygen when they are breathing.

• To communicate with other puffer fish.

• To protect themselves and scare their predators away.

River is a place where we can naturally find flowing water which will end up in sea, lake, or

another river. River consists of fresh water with many natural resources. What kind of

things we cannot utilize from the river?

• The soil as natural fertilizer for plant

• The small stones as construction material

• The fish and shrimp as the sources of protein

• The water as the source to water rice field

Ecosystem is a geographic area where plants, animals, and other organisms live together

with abiotic components and interact with each other. There are many kinds of ecosystem

exist on the Earth. Ocean, rain forest, and desert are the examples of ecosystem where

they have different kinds of population and community. Which one of the following options

correctly shows the examples of populations which live in a pond ecosystem?

• Snail, duck, cod fish, water lily

• Duck, tadpoles, frog, lotus

• Snail, frog, clownfish, water lily

• Swan, tadpoles, coral, lotus
